[−][src]Struct gpu_allocator::SubAllocation
Implementations
impl SubAllocation
[src]
pub unsafe fn memory(&self) -> DeviceMemory
[src]
Returns the vk::DeviceMemory
object that is backing this allocation.
This memory object can be shared with multiple other allocations and shouldn't be free'd (or allocated from)
without this library, because that will lead to undefined behavior.
Safety
The result of this function can safely be used to pass into bind_buffer_memory
(vkBindBufferMemory
),
bind_texture_memory
(vkBindTextureMemory
) etc. It's exposed for this reason. Keep in mind to also
pass Self::offset()
along to those.
pub fn offset(&self) -> u64
[src]
Returns the offset of the allocation on the vk::DeviceMemory. When binding the memory to a buffer or image, this offset needs to be supplied as well.
pub fn size(&self) -> u64
[src]
Returns the size of the allocation
pub fn mapped_ptr(&self) -> Option<NonNull<c_void>>
[src]
Returns a valid mapped pointer if the memory is host visible, otherwise it will return None. The pointer already points to the exact memory region of the suballocation, so no offset needs to be applied.
pub fn mapped_slice(&self) -> Option<&[u8]>
[src]
Returns a valid mapped slice if the memory is host visible, otherwise it will return None. The slice already references the exact memory region of the suballocation, so no offset needs to be applied.
pub fn mapped_slice_mut(&mut self) -> Option<&mut [u8]>
[src]
Returns a valid mapped mutable slice if the memory is host visible, otherwise it will return None. The slice already references the exact memory region of the suballocation, so no offset needs to be applied.
pub fn is_null(&self) -> bool
